GAS-CONTROLLING APPARATUS.

Application led January 24, 1908. Serial No. 412,389.

To all 'whom it may concern:

Be it known that I, HENRY SIEBEN, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Gas-Controlling Apparatus, of which the following is a speciication.

This invention relates to apparatus and m Objectis to produce apparatus designed or use in connection with buildings to permit the gas-supply therefor to be cut o manually in the event of lire or which will automatically cut oil such supply of gas in the event that it is subjected to a predetermined heat.

With this general object in view the invention consists in certain novel and peculiar features of construction and organization as hereinafter described and claimed, `and in order that it may be fully understood reference is to be had to the accompanying drawing, in Which,

Figure 1, is a sectional view of a part of a building and of part of gas-'controlling apparatus embodying my in vntion. Fig. 2, is a section on the line H -II of Eig. t1. Fig. 3, is a detail perspective View of'a/ bracket foi-ming part oftheapparatus. Fig. 4, is an enlarged section of one of the elbows of the calde-protecting conduits forming part of the apparatus.

In the said drawings, 1 indicates the gas pipe leading from the main to a valve casing gas-controlling 2, the house pipe 3 leadingfrom the casingA into the building asshown or in anyother suitable or preferred manner. The valve has a perforated diaphragm between pipes 1 and 3 and below the perforation of the diaphragm is equipped with a removable cup 5 having its chamber reduced to provide the guide passage 6 for the stem 7 of valve 8, the said stem being equipped with a spring 9 bearing at its lower end u on thc valve and at its upper end against tie cap 10 closing an opening in the valve casing above the diaphragin and forming in conjunction with and stulling box for the valve stem. The spring tends to seat the valve and cut olf the supply of gas from pipe 1 to pipe 3 and to coperate with said Specification of Letters Patent.

v and so secured Patented Nov. 10, 1908.

REISSUED spring in closing the valve the stem may also be provided with a weight 12.

'1`o hold the valve unseated normally a part such as roller 13 is carried by an angle bracket 13 secured by a fusible substance to the valve stem, the roller resting upon the cam trackway 14 of a reciprocatory bar 15 mounted in guides 16 of a bracket consisting of a base 17 and angle arms 18 projecting from opposite sides of the base and formed integral with or carrying the guides 16. he base is adapted to rest upon the valve casing and be clamped thereon by cap 10 having a central hole 19 through which the lower part of the cap depends: The base is also provided with a circular series of holes 20 through two of which the screw bolts 21 extend down into the valve casing to prevent 'turning orswivel movement of the bracket on the casing, it being apparent that by the provision of a.j plurality of holes 20 the bracket can be lfaced in different directions by the saine pair of screw bolts 21. The guides 1G terminate in circular heads 22 to receive the ends of a pair of similar conduits preferably consisting of tubes 23 connected by elbows 24 and leading to any point desired. The elbows in their inner sides are slotted as at 25 to conveniently receive guide rollers 20, the parts buingso prolwrtioned that the cords hereinafter referred to, cannot be disengaged from the rollers. As shown the ends of the conduits-opposite to the circular heads 22 ot' said bracket, extend through the wall of the building contiguous to which the valve is arranged and into which the supply pipe 3 extends.

A box receives the ends of the conduits --and by preference consists oi a base 27 and a body portion 28. The latter is preference to the base to be locked in any suitable manner to said base to prevent any butan authorized pci'- son from opening the box.

'.lhe outer face ol the box is oi glass by preference as at 30, so that any one unable to open the box in the proper nnuuu-r may obtain access to it by breaking said glass, il

hinged by at 2!) and is adapted being understood in this eoniuctiou that the bok by preference is localed in the ball- The opposite end of cord or cable Eil is pref-v erably secured in the tube 33 and the corresponding end of cord or cable is secured in any suitable manner to a tube 23st, which tubes project into the box and are respectively equipped with heads or handles 35 and 3G. By securing the cords or cablesr to the tubes fand 34- respectively they never become exposed in the box when said handles or heads are pulled forwardand consequently cannot sag from the front ends,` of the conduits and thus interfere with the quick and free operation of the slide bar, 15.

-When the slide bar is in the position shown, handle 36 is drawn forward I'and .handle is in contact with the contiguous xend of its respective conduit. Should the building take ytire and gain considerable headway before it was discovered and the heat rise to a predetermined point, the connection between the valve stem and the angle bracket 13 would fuse and as a result 'he valve Would automatically close and cut oill the supply of gas to the building. Should the house occupant discover the tire before the heat was suiicient to fuse the connection mentioned, he could open the box and grasp and pull'forward handle 35 and by so doingl he would slide bar l5 to the right and permit the valve to close. Should the occupant fail to roperate the bar any other person such as a fireman, obtaininr entrance to the building, could break the glass 30 and then grasp the handle 35 and pull it forward, it being understood that when this action occurs the handle 3G is of course drawn rearward.'l`o reset the valve in the event that the bracket 131- remained fastened to the valve stem, the handle 36 would be drawn forward, this action reversing the operation of bar 15 and causing cam 14 to engage the roller K13 and force the same and hence valve 8 upward to their original positions.

By the arrangement described it will be lseen that the cords or cables are fully pro.- tected from accidental or intentional injuryl as access can not be had to break or cut them. As a further precautionary measure,'

being detached.

parts from being tampered with. It will furthermore serve to catch the bracket 13a should it become detached and thus avoid the chance of the same being lost as the same bracket. can be resecured in position after From the above description it. will be apparent that l have produced gas controlling apparatus embodying the features of advantage enumerated and l wish it to be understood that I do not desire to be restricted to the exact details of construction shown and described as various modifica tions will suggest themselves to one skilled*y in the art. j

In an apparatus of the character described, a pair 'of pipes, a valve, yielding means tending to cause the valve to close communication between the pipes, a part fusibly connected with the valve, a' cam-bar engaging said part and normally holding ffl valve unseated, a box, and suitablygaided flexible connections projecting into said box at one end and attached at their opposite ends to opposite ends 'of said eambar to move the same in one direction to perlnit the valve to be seated or in the opposite direction to raise said part and therefore the valve from its seat.
